The Sun Hydraulics DMDALAV211 (DMDALAV211) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust industrial applications. This direct-acting, balanced spool directional valve is notable for its fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure environments. The valve features a closed transition between positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The DMDALAV211 operates without requiring a minimum hydraulic pressure, facilitating its use in various fluid power systems. It incorporates manual override options with a detent mechanism designed for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. Special attention is needed regarding the seal material; cartridges configured with EPDM seals are intended specifically for systems using phosphate ester fluids and must avoid contact with petroleum-based substances to prevent damage. This model utilizes a wet armature design where the working fluid surrounds the armature, which could lead to the breakdown of certain fluid types under prolonged exposure to heat from an energized coil. The valve's design also includes interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction to minimize internal binding due to installation variances. Key specifications include a flow capacity of 12 gpm (45 L/min), rapid response times typically around 50 ms, and maximum operating pressures up to 5000 psi (350 bar). The valve also supports high switching frequencies up to 15,000 cycles per hour. These features make the DMDALAV211 exceptionally well-suited for demanding applications requiring precise control and reliability under pressure.
